Posted on January 08, 2017 at 20:53 Edit: compilable example code posted below in comments. The problem now with this code is that too many messages are being sent in addition to the wrong data being sent. I am using VisualGDB and a STM32F303RET6...
Posted on January 10, 2017 at 10:07Hi,I should read output data from an IC with SPI protocol as shown below.Actually I've got confused how can read each bits with SPI for (n=16 to 32). Or can we another simple approach to read data?I did some settin...
Posted on January 09, 2017 at 18:22Hello, I am using USART between the STM32L4 and the Raspberry Pi to enter in the bootloader mode.It is working with the external reset (NRST pin) but I am trying now to enter in this mode with a software reset. I a...
Posted on January 09, 2017 at 15:23Hello,I am looking for a way to generate a CRC after compilation and add it to the hex file at a specified address so that it can altogether be programmed to flash and at runtime can be compared to a value calculat...
