ADXL354 MKR1000

The Brief Equipment Mkr1000(Arduino) Ads1256 (Texas instruments) Outcome required Ratiometric analog to digital converter ADS1256 will send SPI protocol data to MKR1000 and can be recorded from a uart connection from the MKR1000 to a PC. The sample rate must be variable but will need to also be able to reach full speed of the ADS1256 which is 30Ksps and will be required for 4 channels of input from an accelerometer. The accelerometer will have an analog output of 1.8v. Therefor the ADS1256 must have a voltage reference to increase accuracy at such low voltage. Your task will mainly be the programming and testing of the stability and simplification of the C code. I don’t require any fancy additions on the program. I just want it to run and to be able to select sample speed by changing it within the code. I don’t want wifi done as I already have this functioning. I really only want data transmission via a lead. Issues found The Uart connection to PC has transmission limits. (can this be overcome via programming and maybe ignoring the standard uart output on the MKR1000 in favour of direct connection). Final selection When I have made the final decision. I will hand over a circuit diagram and all the relevant data to do with the ADS1256 and MKR1000 including example codes available. We will then work as a team to resolve these issues and will hope that it can be resolved quickly.
