I am trying to calibrate 512Hz RTC to 1ppm or <1ppm. Desired Frequency = 512HzAverage Frequency Obtained is = 512.0073HzWhat should be the value of CALP and CALM ??? (I used the CALP = 0 and CALM = 15, but still the ppm that I obtained is ~14) Could...
Hi, I want to generate a bipolar square wave with a pulse width of 100us per phase using the DAC in STM32F446RET6. But when I measured the DAC output (PA4), I found that the DAC output was not an ideal square wave, but a trapezoidal shape w...
MCU: STM32N6Register: RCC reset duration control register (RCC_RDCR)Bits 27:24 EADLY[3:0]: External access delayThe bit field is security-protected by the 1 bit. Set and reset by software.Time to wait before the BOOTROM performs any external device a...
Hello everyone,I’m working on an STM32F7 project where I’m trying to establish USB communication between my STM32F746 Discovery board and a PC. I am really new at this really first time. I have configured the board for USB_OTG_FS in STM32CubeMX, and ...
Hello at everyone,I setup on CUBE Ide on STM32C011 mcu without the configurator TIMER1 and I would to manage it on update interrupt, but I have not the stm32c0xx_it.c file that would contain the irqHandler routines.In this case, how the compiler iden...
Hello all,I’m working with an STM32 microcontroller (specifically the STM32H743), and I have a question regarding the use of an external TCXO as the HSE clock source.As per the datasheet, when using an external clock source (such as a TCXO), the HSE ...
My question is that stm32g0b1cct6 have fdcan2 or not because i getting confuse i read many document and reference some are said that stm32g0b1cct6 is low budget mcu and its have only fdcan1 not fdcan2 . so dear support team plz response fast regard V...
Hello.. i m programming F446 using registers, and i found from F446 reference manual to configure PA1 as both input and pull-down mode. i don't understand , can anyone advise how could1. MODER &= ~(3<<2) is to set MODER1 as 00 input? 2. PUPDR |= (1...
Objective:Use ethernet cable to talk to MCU.Don't want RTOS, just want to use simple CAT5e cable to link to PC server and can ping and can send some messages to and from server via JSON format messages.I have swept through nearly all available thread...
I’ve written code that performs a CAN Tx transmission when an interrupt occurs while in STOP2 mode.The transmission request via HAL_FDCAN_AddMessageToTxFifoQ() succeeds,but the HAL_FDCAN_TxEventFifoCallback(FDCAN_HandleTypeDef *hfdcan, uint32_t TxEve...
