I need to get 5 miliseconds data (625000 values of 14 bit each), each time I press a button B1, until DDR3 memory is full. The B1 button must be usable again only after the 5ms of data storing ended. An index counter must be incremented with 625000.
If I press a button B2, data must be sent to UART at 115200 baudrate, from memory index 0 to
current index (multiples of 625000). The index will NOT be resetted, so the B2 button can be pressed as many time as needed, to download data.
Data sent to UART must be encoded like this:
0 (not used zero) + 0 (not used zero) + 14bit ADC data from DDR3 = 16 bits
And the sending:
MSB 8bit + LSB 8bit + CHECKSUM8(MSBLSB) + \n
uint8 + uint8 + uint8 + \n
After each 1000 octets sent to UART a small delay must be inserted (we test the delay time), so that the PC buffer don't get overflow.
If I press a button B3, the index counter reset to zero, so I can start again storing data.
The aquisition speed is 125Msps, at 14bit.
Hey there,
We are an engineering firm and have worked on many challenging projects and we can certainly implement any complex requirements with ease though I would request you to let me know your availability so that we can schedule our chat accordingly and discuss the project scope in detail .
Please check the portfolio listed on profile , you can get the glimpse of the technologies we have worked along with the type of projects .
The proposed amount for the project is just a placeholder and the actual amount will be disclosed once we have the complete set of requirements
Look forward to hearing from you..!!
Thank you,
