We have a pcb deisng with firmware that works quite well, we would like to add a couple of features (additional input contact and ntc reading) and so a redesign and a firmware change is required. We need a development company with a lot of experience with pcb design and atmel platform. No prototype needed, we will take care of that. Please begin you bid with atmel, to be sure you read the above. Otherwise your bid will not be considered. Many thanks
I am looking for a professional Atmel firmware engineer with experience in Zigbee protocol. Our custom board is designed to send data over Zigbee. The other parts are working great. We just have an issue in Zigbee communication. It is mainly related with the Zigbee message packet. I can provide with the existing Atmel source code. The task is to review the existing project and resolve the Zigbee communication issue. Only apply if you have experience with Zigbee. To prove that you are serious, please start your proposal with a word "zigbee".
The scope of the project is described in the attached pdf
Solve the null reference issues in the source code. Below is the attached file for the exact issue. We have been building on the Javacard platform since the past 3 years. Keywords - jcop3, nxp, smartcard, javacard
A cyclic buffer working with DMA to send and receive from an UART (SERCOM). Seperate buffer for sending and receiving. Working on the SAM4L8-XPRO board and for the SAM4C Series. Written in C, fully bare metal (no intermediate libraries). Wrapping of buffer handled with DMA interrupts. Handling buffer boundaries (no override of input / output area). Functions to grab buffer In and Out position. And to specify the amount of data to be send (mainly end-pointer or count of characters). Additionaly UART setup routine (only Baudrate). For the project I provide additional specification as PDF as attached.

Guten Tag, für ein bestehendes Projekt suche ich einen C Programmierer um einige Änderungen vorzunehmen. Ich glaube es ist in C geschrieben :-) Chip: ATXMEGA128A4U-MH Hier ein Auszug aus der main.c /** * file * * brief PS2-101 Ps - application entry point * */ /* * Include header files for all drivers that have been imported from * Atmel Software Framework (ASF). */ #include <asf.h> #include "as3911.h" #include "as3911_com.h" #include "as3911_interrupt.h" #include "iso14443a.h" #include "clock.h" #include "ic.h" #include "uart.h" #include "delay_wrapper.h" #include "sorex_hal/Communication/Rfid.h" #include "utils/debug.h" #include "utils/reschedule....
The project is to add the circuit into existing PCB. The circuit is offered. The designer will update the schematic and PCB. And if you know about firmware development for ATXMEGA128AiU and Atmel studio 7, it is preferred.
The project is about programming an operational flow in an ATmega128 Atmel Micro-Controller. Application is controlled via a Nextion Touch Display. As per input on display, complete operation is to be executed to turn ON/OFF the peripherals. Number of Peripherals to be controlled: Digital Output: 17 (ON/OFF or HIGH/LOW) Digital Input: 07 (HIGH/LOW) Analog Input: 04 Nextion Touch Display GUI & Atmel128 Arduino IDE code is implemented. Freelancer just need to implement process level flow program. Request to freelancer to ask for more operation level details if interested.
Need an example written for a SAML22 processor using ASF4 which allows for a multiple-input 12bit ADC reading. It is simple for anybody who knows Atmel products. Need to be able to read and convert a set of ADC inputs. Must have experience with AMM and SAM processors.
Assistance needed in porting code written for a PIC18F26K to a more modern model (that is in stock). Program is about 400 lines of C, I suspect the model number may need to be changed and a few pins remapped, but otherwise the code is usable. Currently using 1 A/D, TX/RX for serial and 4 GPIO pins. The code is doing battery management. If it is less time the code could be ported to Atmel or Arduino if decided, it is not doing a whole lot. Bonus points if you are familiar with Raspberry Pi. This project sends data via serial to the Pi and that also needs some updates. Can discuss that further after this is completed.
The task consist to create a bootloader for the SAMD21E17A Microcontroller based on the Microsoft/Adafruit UF2 Bootloader. It needs to be compatible with Arduino for uploading the code, customer requirement. The bootloader has been compiled, however there is no way to communicate with Arduino IDE. Variants were based on TAU and Trinket m0, no luck. It will be probably an easy fix, but I am stuck with it. Looks like some linker script or BOSSA configuration is wrong. I will share my code with you if you need it. Required skills/equipment: - linux/unix environment - C language - Development board with SAMD21E18 or E17 (not a must)
Description : Android device needs to use the certificate located on the SmartCard to authenticate using HTTPS proctocol. The certificate can be accessed from the PKI Applet using PKSC#11 API. The certificate is loaded in the slot / token structure on the PKI Applet and is protected with a PIN. The Smart Card is inserted into the P/SAM reader of the Android device. Requirements : - use the certificate from the PKI Applet on the Smart Card to establish SSL/TLS connection on Android - the solution for extracting the certificate used to authenticate needs to be APDU based (ISO/IEC 7816-4 standard) - deliver a test application where the given certificate is used to successfully authenticate with the given test url The needed Smart Card will be provided (based on J2D081), as well as th...

...The most important tool in the WDK is the SignTool. It is used for signing and potentially verifying drivers. Microsoft advises against using a certificate file (PFX) for signature purposes; instead, it recommends importing the certificate into the operating system’s certificate store and then performing the signature process.

"Kernel-Mode Code Signing Requirements during Development and Test 64-bit versions of Windows starting with Windows Vista The kernel-mode code signing policy requires that a kernel-mode driver be test-signed and that test-signing is enabled.

Hi, We are looking for multiple writers to write on technical topics. ** The writer must have practical experience with microcontrollers i.e. Arduino, PIC, Atmel etc. ** Please mention at the start, on which platform, you would like to write. We will provide order in bulk so looking for low prices. Thanks.
...detected from MPU 6050 and play audio tracks from MKRZero's onboard SD Card. Audio tracks need to play for: 1.) at least 1 track and, 2.) keep playing track after track while motion is detected only stop playing when motion is no longer above threshold, at which point, MKRZero returns to sleep. (if possible make the threshold for "motion" easy to change) Needs to be written for Arduino IDE or Atmel Studio 7. Below are some simple examples to help (if needed) - Simple audio player MKRZero: (This is how I wired up speaker, so code may just need copied) - Read SD Card MKRZero: - SAM example
We are a small manufacturing company producing unique and hand-made sound instruments, i.e. analog synthesizers. Our brand name is "Club Of The Knobs - Modular Analog Synthesizer" Some of our modules need Atmel chips to control functions on the boards. We need them programmed again since we have lost the previous versions. We therefore know the exact requirements for the chips and can provide the circuit schematic for the electronic environment. We are looking for someone who also knows electronics and can make the connection between the digital and the analogue.
I'm looking to do two things. 1) To create a msc bootloader for the device that a user can interact with and 2) To set up a basic project file where I can interact with the onboard IO and components (accelerometor, buzzer, vibration motor, and move files back and forth from hidden to visible msc memory). background information: There is a 2MB flash memory chip which displays 1MB to ...all the building blocks to begin building a device program. many, if not all of these requests are already premade libraries.
