This week I fix my ADC driver, which I done it incorrectly previously. PIC32MZ come with 2 different Family namely the ‘EC’ family and ‘EF ‘ family. The main difference for both of them would be ‘EC’ only capable of 10bit ADC conversion while ‘EF’ can up to 12bit ADC. For my Read more…
This week I continue doing emulating ADC based on the proper protocol of SPI ADC from Microchip – MCP3204/3208 From the document table 5-1: state that to initiate a ADC read for specific channel, Master SPI will first send 4bit of ‘Control Bit Selection’ to read the data of the particular Read more…
This week I did some programming on PIC32 ADC and SPI functions. The goal is to transfer ADC value from PIC through SPI to a FPGA chip. FPGA chip will act as a ‘Master’ while PIC32 will be the ‘Slave’. I will be coding for PIC32 only therefore the following Read more…
Week Four! How time flies, it’s been nearly a month since I first stepped into the office of Aeste. Continuing from our previous work of setting up a basic SPI bus between a Raspberry Pi (RPi) master and a PIC18 slave, we go on to write a function for the Read more…
