Good morning,I'm using 5V-tolerant Pins on the STM32F405xx for my 5V Pulled-up I2C Bus. The Vdd for the STM32 will be generated by a LDO out of a 5V supply. According to AN4899 ("GPIO electrical characteristics and definitions") [p. 19/20], you shoul...
I've hung a 32.768kHz crystal (IQD) on to my STM32F767VGT6 with a pair of 10pF caps as per AN2867, but I'm not getting the LSE to oscillate. If I route the LSE to an MCO output I see random transitions, which explains why the RCC status bit shows it'...
I want to blink a LED and I have written this code:#include "stm32f10x.h"int main(){ // initialize the clock for Port C RCC->APB2ENR |= (1<<4); // enable clock for GPIO C ( check it on memory and bus architecture) // set pin 9 of GPIOC ...
Hi, Kindly tell me the part number of STM32H7 development board or share me the link.Thank you
What I want to implement is to control the role of the module between host and consumer, when modules are connected to each other. Is it possible with programming ?If impossible with this module, what module can I use to implement that task ? Thank y...
I am using STM32F779NI for my project.https://www.st.com/resource/en/application_note/dm00315319-stm32-gpio-configuration-for-hardware-settings-and-lowpower-consumption-stmicroelectronics.pdf Section 6.1 of above pdf states that unused input GPIO sho...
Hi,the IPR bit assignment in 'PM0253 Rev 5 p.189' tells me that a number of bits [n-1:0] are read as zero and ignore writes.At this point n isn't 'n = m MOD 4'.Obviously n is 4 because i can write only the four upper bits and bits [3:0] stay at zero....
I've tried __attribute__((constructor)) on STM32F030R8T6 for running tests like Gtest framework by user-defined test. The code is shown as below: #define TEST(name) \ void Test##name(void); ...
I am using ADC2 Channel 10 with external trigger TIMER 2 TRGO Update. Although I am viewing the ADC values over USART and it is sampled but the sampling time is not 2Hz. Which I set in TIMER 2 just to make sure that I can control the sampling time vi...
I believe I am doing something wrong. I read that to re-write to the RTC I will need to:1. Write ‘0xCA’ into the RTC_WPR register.2. Write ‘0x53’ into the RTC_WPR registerI found a function in the RTC file that is:#define __HAL_RTC_WRITEPROTECTION_DI...
