I'm using STM32F407 as a USB host. I have multiple devices in which we are using CH340E as the USB to serial communication. The problem is if that device somehow turns off and CH340E loses its power. The USB Host can not transmit data to the other de...
hi,The datasheet says "In this mode, the TCR flag is set when the number of bytes programmed in NBYTES is transferred"Does this mean that the flag will be set when the data is transferred from TXDR to shift register, Or, the flag will be only set if ...
Hi,I've been using stand-alone RTCs that clearly indicate through a specific bit whether the date is correct or may have been corrupted by undervoltage.I cannot find any clear indication of a similar feature for the RTC integrated in the STM32F446 (u...
Can we use the Internal ADC Vref channel and External analog input channel simultaneously in STM32L053R8 and get data using DMA.?
Hi, I'm using an STM32L053R6Tx chipI've implemented at TMR2_interrupt hander it gets triggered on ARR overflow and CC1FI'm using the interrupt to trigger a GPIO output to work like a PWM the- GPIO is high when CNT is less than CCR1- GPIO is low when ...
I'm new to using the Nucleo environment I am not seeing any activity on the PB10 and PB11 when using the SMBUS_TwoBoards_ComIT_Master example, when looking at those pins on a scope. I only have one board currently. - Board: NUCLEO-U575ZI-Q (embeds...
Hello,I've been doing a small project lately and ran into a problem in one part. I have two STM32 microcontrollers and I want to communicate both of them with eachother over UART. One of them is designed to send a fixed array of 6 charactersuint8_t k...
Hello, My STM32F7 crash after Reinit the UART : - I have an UART for my RS232, and I can communicate to 2 devices by this RS232. So the customers choose on which device he want to send data, then I configure internals variables and the UART baudrate ...
Hi community,I have a problem where Ethernet does not work when VOS is set from scale3 to scale2 or scale1 on a customer board.Please help us solve the problem. Clock and peripheral settings use code generated with CubeMX v6.9.1. The CPU is STM32H745...
All:We have a custom board with STM32H723 where VREF+ is set to 3 volts.When I feed ADC3 input 2 with a value of 0 volts, I get 118 counts on the 12-bit ADC, 1.48 volts gives 1385 counts, and 2.95 volts gives 2600 counts.Earlier work with Nucleo boa...
