...embedded software. The immediate focus is fixing, real-time data exchange over RS422, RS485, and DMX / Art-Net / sACN. GPIO handling and A/D sampling. We have code from a older version of the software which requires bug-fixing to match the output of the newer version. What will make you successful here is deep, hands-on experience—ten years or more—with C++ on ARM microcontrollers, familiarity with Atmel toolchains, and a background that spans both firmware and board-level design. You should already have a complete development environment; I can ship the target hardware for validation and regression testing. Because this project involves interactive debugging with my in-house team, I need you available during Pacific Standard Time work hours for code reviews and li...

I have a mature code-base running on a Microchip SAME54 (Cortex-M4) that now needs to live on a SAME70 (Cortex-M7) board. All reference manuals, schematics and pin-maps for both targets are on hand, as well as the full current project tree built under Atmel Studio / ASF4. Your task is to migrate the project so it compiles cleanly for the SAME70, boots reliably, and exercises every peripheral we use today. Once the build is stable, I’d like you to stay on for a short joint test phase where we flash the new board, run through my existing regression scripts, and iron out anything that surfaces. Peripherals that must be verified after the port: • Analog-to-Digital Converters (ADC) • Pulse Width Modulation (PWM) • Serial Communication (UART / SPI / I2C) ...

...the SAME70. Every source file, driver, middleware component, and RTOS hook that currently runs on the SAME54 must compile and execute on the SAME70 without functional regressions. Once the code is building cleanly, I’ll also want your help running it on the new hardware, checking peripheral behaviour, and ironing out any runtime issues that appear. The current project was built in Microchip-/Atmel Studio using ASF 4 and CMSIS, so experience with those environments—as well as the tool-chain for Cortex-M microcontrollers—is important. You’re free to introduce additional tools (e.g. MPLAB X, IAR, Segger Ozone) if they speed the process, as long as the end result remains buildable by me in my existing setup. Please be ready to: • migrate the full so...

...interfaced to an ATTiny84A. Only 6 positions are to be used, and the position will be queued up with a single push button. The purpose of the dial is to provide input selection, to the ATTiny84A and will turn on power to either 1 or 2, of 3 PORTB pins. This will also require adjustment of PWM on several pins that I will need to adjust several times through the project. I would prefer this be done in Atmel studios as that is what I use, but any format in which I can adjust the duty cycle would be sufficient. This will most likely require software PWM on PB0 due to the use of PB0 through PB2. All the electronics for this project are in breadboard testing and can easily be changed if necessary. I have started writing AVR C code for this. However I am not nearly as proficient in AV...

I want to generate an I2C slave with a SAMD21. This should have write and readable registers. Unfortunately I can't get this to work. I was guided by the following code: From page 39: The final application “High speed Configuration” in main.c file will be as below for SLAVE. The aim is to provide 256 registers (1 byte in size) with the SAMD21 (as Slave). The I2C master can write and read these registers. Your task is to create this functionality based on the provided example. Only the function "void SERCOM2_Handler(void)" may be adjusted. The I2C master works in FAST_MODE_PLUS. Therefore, the rest of the configuration must remain exactly the same.
