Hi I have am using the Timer2 on the STM32L433 chip, and for some reason the interupt gets called as soon as timer is started. Below is my code, and the clocks are running at 60MHz. Anyone any idea what I have done wrong? Many ThanksScott. void m...
Hello,due to pin shortage, I (foolishly) used pin PC14 and PC15 as output GPIOs on a board that I designed and my colleague is writing the firmware. We never use them previously, due to the all problems with limited sourcing caused by internal backup...
Hi everyone,I’ve been working in IT for a while, focusing mainly on cloud computing and Linux environments. However, I’ve recently become really interested in embedded systems and the potential for integrating hardware and software solutions.I came a...
So I've got a program with a fast tight loop doing some minimal things, and the rest is housekeeping/UI stuff in the main loop. When I enabled ICACHE, the speed of the tight loop increased DRAMATICALLY and overall the process is faster at basically e...
Datasheet for the Macronix flash is not available on-line. Can someone tell me about the correct parameters needed for the Macronix MX66UW1G flash?The number of sectors (used 32), sector size (used 4096), page size (used 0x100), chip select high time...
uint8_t my_buffer[ 1B_LEN_PREFIX + 24B_LEN_DATA + nB_LEN_SUFFIX ] = {0}; (void) HAL_SPI_TRANSMIT_DMA(&hspi2, &my_buffer[0], sizeof(my_buffer)); I'm using the SPI TX line only to drive an addressable LED, making a custom waveform from SPI bits to...
It's a niche application. STM32H5 QFNI need SPI2_MOSI to make a specifically shaped wave. SPI is works well for this. I do not need the SPI_CLK pin/function. I set Cube MX to SPI2 Transmit Only Master, and of course it applies the CLK pin because alm...
Hi Team, I am working on STM32U5A9J-DK for one of our applications interfaces with an Octal flash via Octal SPI. we were able to communicate and do the flash operations Read write using the SDR mode . Now to achieve the DTR mode from STM32U5a9 end ...
How does the (USART_ISR) BUSY flag get reset? The data sheet indicates "end of reception," but that is not defined. Is it an end-of-frame, idle event, or something else?
