Posted on May 31, 2018 at 11:19My current project using STM32L071RB chip, and now encounter a strange issue, when I enable PWR_CR ULP bit thr 'HAL_PWREx_EnableUltraLowPower()', the systick (Using TIM2 as timebase) become slow. and if I disable ULP b...
Posted on May 31, 2018 at 14:02I am working on STM32F030Xc MCU. Which I set UART settings as: 7- bit, None parity, 2 stop bits, And its connected with PC terminal with settings 7-bit, Even parity, One stop bit. So both MCU and PC should not communic...
Posted on May 01, 2018 at 04:19I have purchased a https://os.mbed.com/platforms/ST-Nucleo-L476RG/ board for evaluating STM32L476XX MCU. However I am interested in the CAN functionality provided by the MCU and my question is do I need CAN transceiver...
Posted on May 09, 2018 at 12:44Hi All,I am working on STM32H743 MCU's DMA.I was doing DMA transfer on the SRAM address space 0x30000000 (data transfer of 16K). I was visualizing a situation where i put this (0x30000000) address of the sram on the fu...
Posted on June 01, 2018 at 08:13I'm using STM32F070RBT USB CDC device to communicate with PC. CDC channel is working fine except one issue. Looks like current channel has 63 character limit. i send 500 characters but i receive only 63 in buffer but ...
Posted on June 01, 2018 at 08:01When an error occurs, e.g. byte alignment, this might not be reproducible on the bench. It happens in the wild, when no debugging is possible.Therefore the idea, all these errors have a common error handler which does...
Posted on June 01, 2018 at 07:55Hi all,The following problem is appearing changing sectors write protection and power disappearing in the middle of a HAL_FLASH_OB_Launch operation. After the next power up, flash options are reset with RDP = 1 and a...
Posted on May 31, 2018 at 10:55Dear all: I am working on the stm32F769 ST board. The gpio output voltage is 3.3v. I want to change the GPIO output voltage to 1.8v. How can I make the change? I would greatly apprieciated.
Posted on May 31, 2018 at 15:40Hi ,I used STM32F103ZET6 PIN28 PC2 ADC funtion to get the voltage of CMP_V. The voltage of this pin(PC2) is 0.032V when R335 is 100 K,CMP_V is olso disconnected from any circuit. I try to change the value of R335 t...
Posted on May 31, 2018 at 22:48Hello, first of all pardon my ignorance, I'm a little new to STM32 development. We are working on a project on an STM32F769, and my EE has asked me to generate a fairly fast (20mhz) clock output on a specific pin (PD2...
