Signa A and B with 90 degree phase shift
Hello dear friends,does any one know how i can have 2 signal with 90 degree phase shift? but i want to use this easy bit pattern to have it and not pwm, just with this bit pattern 00, 01, 11, 10, and also a sleep time for delay, it shouldn't be diffi...
Resolved! Using both CAN1 & CAN2 both in STM32F446RC
Hi, I want to use both CAN1 and CAN2 for my application with 500kbps and 125kbps speeds respectively. I have initialized both of them as per my requirements using HAL. Where in Tx is implemented in polling and Rx in interrupts. CAN1 Tx and Rx working...
Resolved! STM32 CANbus is not sending/receiving message
I am trying to send messages from Can1 to Can2 in an stm32f205vet6. HAL_CAN_AddTxMessage is returning HAL_OK but I am not able to receive any messages in CAN2. And I cant see any messages transmitted in a scope. clock speed = 120MhzCan speed = 500 kb...
How to transmit and received data using CAN2 in STM32F40ZGT?.
I have successfully transmit and received data using CAN1. But having problem with CAN2.I have go through all the configuration to enable the CAN2 however, I unable to transmit the data through CAN2. What I have done:1) Enable CAN2 ( PB12 [Rx], PB13 ...
Resolved! ADC sampling frequency - STM32H743ZIT
Hi,I use ADC3 on STM32H7, I need to know (and set) what is sampling frequency.I use 3 channels in 16 bits. What I tried to calculate?1) Tconv_time = 8.5(setable)+8.5(fixed for 16 bits) = 17 ADC clock cycles = 17/30Mhz = 566 ns2) From this image I sho...
STM32F103 NRST PIN CAPACITOR VALUE?
There was a phenomenon that booting was not possible during the low temperature test.The NRST external switch is equipped with a 100pF capacitor.The datasheet recommends installing 100nF.However, I don't think it will be a problem because the MIN val...
Resolved! STM32F072 Clock tree section shows how to select clock for USARTS 1-3, but not USART4. Were in the reference manual (RM0091 Rev 10) does it show how to select the clock source for USART4?
The USART section states that all 4 USARTs can be clocked from a common set of 4 clock sources, but doesn't reference how to specify the clock for USART4 either.
Resolved! STM32F072: where is "APB1 prescaler" defined in the Reference Manual?
The STM32F072 Clock tree figure in reference manual shows APB1 prescaler, but where is that defined in the reference manual? When I search for APB1 in the reference manual, in the context of a register field, it does not show up (other than in the cl...
