I'm taking my first steps as an embedded engineer, especially in STM32. I've been looking for a specialization that will give me more experience, in addition to the 35 years I have in IT (Client/Server) and about 10 in embedded systems.I'm currently...
when I am using frequency 266mhz after that I am sending the string Hello world in 0XC000000 0 but in address, 0xC0000080 appears again, can you help me with the case?thanks
i have written a driver code to run 4 wire resistive touch panel. I use only 1 adc and change its adc channel during runtime. Like i set X+ and Y+ as output high by default and X- and Y- set as low by default and set X- and y- pull down to make ADC r...
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...
