In STM32F767VI can i send CAN data from CAN1 to CAN3/CAN2 and viceversa. I get ACK error when i try it.
I'm using the STM32F765VIT in a custom board and Trying to test CAN1 CAN2 and CAN3. Is it possible for me to send CAN data from CAN1 to CAN2/CAN3 and vice versa? I have CAN transceivers in them if you had that doubt. I'm trying to send data from CAN1...
Using interrupts (too quickly) prevents PWM from working?
I fixed my mistakes from my last iteration of code (reduced 6MHz interrupt rate (which is impossible) to around 35KHz,) and reduced the amount of code in the interrupt. PWM on any timer still refuses to work even though I've enabled them. Is it possi...
STM32H7 IWDG is not disabled after software reset.
My application requires to be started without watchdog enabled (don't ask why). But it seems that once enabled, after a software reset the IWDG continues to run, and if not treated in time causes to another reset. Note that the "Hardware watchdog�? ...
STM32 ADC power supply
Customer asks me to use STM32 powered from 3.3V with ADC reference 3.3V too (different source). So there is two possibel topologies:Connect VDD and VDDA, use precision source for VREFConnect VDDA and VREF to precision source, VDD connect to standard ...
How to use 1 channel encoder on STM32F103?
Hello, I'm using STM32F103 on CUBE MX, when I used an encoder which has only 1 channel, nothing was added to encoder register. I get data from this function: __HAL_TIM_GET_COUNTER(&htim3). So does it has any different when we config encoder mode with...
Export restrictions on STM32 MCUs?
I ordered a bunch of STM32L443CCU6 chips from element14. I got an email from them saying that there are export restrictions on the chips. I’m based in India. How do I get these chips now?

Hey, I'm using TrueStudio and I'm trying to program BOOT_ADD0 and BOOT_ADD1 by software so I can enable the bootloader and be able to use dfuse to upload new firmware using usb without using the ST-Link Utility to program the option bytes.So far, whe...
RM0383 Rev 3 3.8.6 Flash option control register (FLASH_OPTCR) maybe wrong default value
To whom it may concern:RM0383 Rev 3 for the STM32F411 on page 63 states as default value for 3.8.6 Flash option control register (FLASH_OPTCR)a default value 0x0FFF AAEDValue read back on a new device is however 0x00FF AAEDThis fits more with bits 2...
Hello ST, i have an issue on I2C Bus. I want to communicate with an external device LTC3350.
I just like to read some internal register of this device after startup and also while application is running. But i2c allways retuns that it is busy and does not start any clocking observed via oscilloscope. Shows me all the time that it is busy reg...
