You can use a MATLAB script to generate the sine table data points or use this online simple calculator. The request req given in argument is analyzed, a response is then built and sent by using the information of the modbus context ctx. However, on the slave side, you can direct the incoming data from SPI to UART using DMA or maybe with polling or interrupt as well. Note that the address should be 0x48 (with A0 tied to ground on the TMP102), but we need to left-shift that byte by 1 bit, as we are using a 7-bit address. The STM32 will be receiving a message (4-6 bytes with no end character) from the UART device every few seconds and then must send a reply.STM32 HAL Driver Receive with Interrupt example Raw stm32_hal_uart_receive_it_example.c # include "stm32f1xx_hal.h" UART_HandleTypeDef UartHandle; /* UART */ __IO ITStatus UartReady = RESET; /* Theyll roll over to the next communication session.
