on the SMT32L475 Discovery kit IoT, I would like to implement the following commands from Arduino:Serial1.begin(BPS, SERIAL_7N2); Serial1.print(msg) while (Serial1.available()) { t = Serial1.read(); wmsg[ct] = t; ct++; *bufflen = ...
Hi,My application is to copy the content (32-bit Data) in the Memory to PORT ODR each time it detects a Falling Edge. I use DMA1 from TIMER CCP pin. The problem I have is, DMA1 will stop as soon as it complete the transfer and require to re-enabling ...
I'm curious to Know before purchasing this Board a few things,Our need is , the Board shall be reliable to adapt the Other Quectel Modules as well like for Indian Bands i.e EC25-E modems from Quectel.The issue is in India, LTE-M is not operational, s...
I am using STM32F407 Discovery Board and I'm generating my project using MX Cube I'm doing testing on I2C sensor that is MLX 640 which is used for taking thermal image , so basically we are are reading frames of thermal image via I2C on every 1 sec...
Hi, i'm trying to use the LSE clock with the RTC but it doesn't start until i make a state reset or run the code under debug mode.I have read all other posts of LSE problems in the forum and found a lot of info, almost everything related with hardwar...
I do some serial interface clock with timers chain on stm32f407.Thats work, but generate little bit lower count of impulses. where is my trouble? len is about 16 384, overall pulse count len*16.I miss about 200*16=3200 pulses.Thank You!TIM2->PSC=0; ...
Hi, Currently i am using STM32L082CZ processor and debugger tools as ST-LINK V2 B2019-51.When I enter debug mode, it will update the status/flag/watch variable upon reach breakpoints. The debugger window show on Keil won't update during run time, i...
I understand the sampling rate for 16-bit can be a maximum of 3.6Msps depending on the chip package, number of ADCs, oversampling, and interleaving or regular.. I'm doing a regular 3 channels 16-bit scan from a single ADC, no oversampling.The app not...
Hello,I am observing a strange behaviour of the first few PWM pulses after a change in duty cycle. I use HAL_TIM_PWM_Stop, HAL_TIM_ConfigChannel (with the changed Pulse) and then HAL_TIM_PWM_Start. What happens is that for around 1 millisecond the ...
