How to read or get an encoder's value without using encoder mode?
Hi all,I am wondering if it is possible to read an encoder using STM32-L476RG without its Enocder-Mode function. If so, how do I do it?Thanks.

When the CAN bus is connected to the inclinometer, STM32 fails to send CAN data.
There are some devices on the swing table on the CAN bus, when connected to the inclinometer, stm32H743 will fail to send CAN data. The phenomenon of checking CAN bus with logic analyzer is that ERR is generated at the CRC or CHECK bit, and the resi...
Resolved! "UM2407 User manual", table 20, "CN9 ZIO Connector pinout" pin name of pin 15 wrong
Table 20, "CN9 ZIO Connector pinout" on page 40 of "UM2407 User manual Rev 2 - STM32H Nucleo-144 boards (MB1364)" lists the wrong pin name for pin CN9-15. It is listing PE0 while it should be listing PE9.
Volts above VCC are dangerous for the ADC
Hi, I’m using a STM32F407G-DISC1 board which has 3V power supply.An ADC measures output of op amp. Output voltage is clamped with 3.3V Zener diode. Is the additional 0.3 volts above VCC dangerous for the ADC?
Resolved! Where could I check the differences between these two chips reviews?
They look the same but I one of them is running the firmware right after plugging the power source, and the other is not. The revision letter is different on both (Y and Z). Is there a way of comparing the changes between both revisions? Thanks in ad...
Does STM32G0x1 have a WKUP3 pin?
Referring to RM0444 and DS12232 (referring to STM32G0x1 programming manual and data sheet).In the Low Power section, the RM states that there are five wakeup pins:But in the register section, there is clear mention of WKUP3 (EWUP3 bit in PWR->CR3, WP...
Resolved! Why are 32 bits timers longer to be set up with pwm mode using DMA burst feature? (F446RE)
Hi, I am using this code, TIM1,3,4,8 are working directly like a charm, but TIM2 and TIM5 the only 32 bits timers are taking approximately 1 minute and 45 seconds to be working. Does anyone know where comes this issue? uint16_t buffer1[12] = {0,35,...
Reading ADC with STM32H750 Discovery Kit
