Resolved! [SOLVED] STM32G030F6 TIM16.1 no output on PB8
I'm trying to get square pulses on PB8 with TIM16.1 output compare, but no pulses on pin (timer seems working: CNT counting, SR flags changing).Setup code:gpio_mode(GPIOB,8, GPIO_MO_AF); gpio_af(GPIOB,8, 2); // PB8 as AF2 rcc_apb2_on(RCC_APB2_TIM16);...
Resolved! EXTI15_10_IRQn triggered constantly - STM32L4R5ZI
Hi, I am trying to write an interrupt code to trigger LED(PB14) using user button on my NUCLEO board(PC13). however, as I observed from the debugger, pending bit for line 13 constantly at 1 without pushing the button at all.The EXTI->PR1 = 1<<13 stil...
How to change the number of ranks after ADC initialization
I use 6 ADCs.I use 3 channels(Ch1, Ch3, Ch13) for ADC1.I use 3 channels(Ch2, Ch4, Ch15) for ADC2.Use DMA1 Channel1, DMA1 Channel2 respectively.DMA1 Channel1 is used by ADC1,Number Of Conversion is 3, Rank 1 = Ch1, Rank 2 = Ch3, Rank3 = Ch13.When usi...
STM32G070 And Bme680 help i2c
hi i'm trying to use the bme680 but i can't find any library for it ,plus the datasheet is so confusing if you had any luck using it please help thanks in advance
How to handle asynchronous (data size of 240000 bytes) data from MQTT in STM32
I am using STM32L475 dev board and SIM7600 4g module. I have implemented MQTT communication in this project. I can successfully connect to MQTT broker and also able to receive the data. But the problem is size of data is large (240000 bytes ie 234.37...
Problems with I2C register code (STM32G0x1)
I am attempting to write register level code to control the I2C peripheral in an STM32G0x1.My read function is failing because the RXNE bit is never getting set. I believe I have implemented the state machine described in RM0444 (p. 958). Is there ...
I have made a target board using STM32G484VE . I am using 11 ADC pins spread across ADC1 - ADC5. I have introduced a 3.3V Zener BZT52-B3V3 as a protection at all ADC inputs, but all the ADC voltages read 0.6V less from the actual voltage ? Any reason ?

[AN2834] Is the LM235 a temperature sensor or voltage reference? (Errata?)
Hi,Maybe the TL431 is a voltage reference.
