why is there such a bad attitude to writing documentation ? check the attach
why is there such a bad attitude to writing documentation ?English is not the main language for me, but even I see a lot of spelling errors in the documentation, are you forbidden to check ?
Analog Comparator False Initial Trigger
Hello,I am working with an STM32G071. I am using Comp2. I have configured it with the STM32CubeIDE. Presently, It is set to "medium" speed/power, and Rising Edge Input with High Hysteresis. The positive input is set to INP/PB6. The negative input is ...
F103 PWM using DMA not working
Hi,I'm usingSTM32CubeIDE 1.6.1Windows 11I can get PWM working using both TIM1_CH1 and TIM2_CH2The frequency and duty cycle are as expected from the settings in the IOC file.However, when I try and do a HAL_TIM_PWM_Stop_DMA(htim, TIM_CHANNEL_1);I get ...
STM32F429 timer Question
im confused about the TIMPRE bit in the RCC_DCKCFGR does it only effect the apb1 and not apb2 timers cause the way it describes this bit it acts like the apb2 can be times 4 because it says PPREx so 1 or 2 but on cube mx im noticing when u enable t...
Resolved! Problem with built-in bootloader over CAN with STM32F466
Hi, i can definitely use a push in the right direction as i am really stuck on this one. Goal is to push new firmware onto a STM32F446 via the built-in bootloader. For this i have connected two MCU's on a CAN bus, the receiving one is a STM32F446. I ...
STM32H750 ADC+DMA Continuous mode PC2_C and PC3_C sampling data is unstable
I'm having some ADC+DMA sampling problems with the H750. When the ADC+DMA is working, in continuous mode, PC2_C(ADC3_CH0) gets 16bit sampling data which is unstable and constantly jumps between 10000+ and 30000+. I guess there is a problem with the ...
How to transmit 2-byte / 16-bit data over HID USB
I came across a nice tutorial (8-bit data) and successfully had the code work with the STM32F103C6/8. Win11 can see it as a joystick. *** Original HID_MOUSE_ReportDesc *** 0xA1, 0x02, // Collection (Logical) 0x05, 0x01, // Usage Page (Generic Ctrl...
SDRAM data Duplicated
Hi,everyone. currently i'm trying to acces IS42S16400J SDRAM using STM32H743ZIT. but i have problem, when i write "01020304" data to C0001000 addres the data was duplicated to addres c0001080,although i didnt write anything on that addres do you guys...
Resolved! STM32H7 Workaround for DMA data transfer > SPI fifo-buffer
Hi! I am working on a project where we are using DMA driven SPI-transmissions. I am using LPTIM1 to synchronize readouts of multiple SPI busses. The setup works when the transmissions is equal or below 128 bits (for SPI1-SPI3). When HAL_DMA_MuxSync...
