Resolved! How to get validation that SPI transmit has TX data on peripheral and is ready for master get it?
I am using the STM32L4S9AII6 clocked at 120MHz. This device is being used as a slave to a master that is clocked at a much higher frequency. They communicate over the SPI1 bus. I am trying to optimize the rate of communication between these two devic...
use of HAL_SPI_Transmit()
I am using HAL_SPI_Transmit() API to write to slave's register, how can I confirm that it has actually find the right register and write to it? is below code right?uint8_t R44=0x2C; //register addressuint8_t R44_data[2]={0x00,0x00};// data to be writ...
Read TCS3200 sensor frequencies with Timer Input Capture
Hello everyone,I'm trying to read the frequencies of the TCS3200 sensor, which should give frequencies according to the colors it detects.The sensor, used with Arduino, works very well, however using it with an STM32G0 I encounter difficulties: when ...
How to restart Normal DMA? STM32L476
Hello...I am collecting 480 samples of multiple channels of A/D1....I want to do this every 60 seconds. I am running in Normal mode because if I stay in Circular mode the A/D data continuously updates even without the trigger which is not what I want...
Jump to bootloader from application on STM32U5
In AN2606 it says:"For STM32 devices having the Dual Bank Boot feature, to jump to system memory from user code the user has first to remap the System Memory bootloader at address 0x00000000 using SYSCFG register (except for STM32F7 Series), then jum...
