How to understand the sacle factor of stm32g4 cordic algorithm? For example,i use the cordic algorithm to calculate Arctangent,but i don't understand why ARG1 is x*2^-n, RES1 is 2^-n *tan^-1 x .I think the correct result is tan^-1(x*2^-n),

Need hiring an expert for implementing stpm32-002 firmware on stm32f103 and stpm32 board

Problem Sending CAN Message

Posted on April 15, 2018 at 23:27I am following the example code found here to send and receive CAN messages:STM32Cube_FW_F4_V1.21.0\Projects\STM324xG_EVAL\Examples\CAN\CAN_Networking\SrcI can happily receive CAN messages but when I call the followi...

Flash Erase without interrupting the ruining application for updating the firmware over UART

Hi Team,System Overview:- We have a system which contains two controller, out of which one is STM32G071. Second controller handles all the wireless operations i.e. Wi-Fi. both the controller communicate over UART to exchange information. Data receive...

Hi, We are using STM32F427IIH7 for one of our project and it is out of stock now. we found an alternate part(STM32F765IIK6) for that but the new part have some additional features like VDDSDMMC and VDDUSB . Also found some diff on PDDR_ON connection.

I can't receive the required ack bit from N2 node. So CAN message can't be transmit from N1 node.

As you can see due to i can't receive the required ack from N2 node, N1 node It keeps sending the same message. Then HAL_ADDTX function returns HAL_CAN_ERROR_PARAM because the transmission is not happening and all mailboxes are full. Also i request T...

input configured pin to detect frequency.

I am using STM32F103C8, in which I want to use pins which are configured as digital input to detect the square wave frequency or the frequency at which the pin is reading high and low.Is it possible without Input capture direct mode?

HAL_GetTick() always return 0 when i use UART

Hi, I work with STM32L562VET6Q, and when i try to comunicate with uart HAL_GetTick() fuction doesn't work because always return 0, but if i don't use uart work perfectly, What could it be due to? I try to change prioritys in NVIC interrput table but ...

STM32F4 + UART + DMA + IDLE detection + High Rates + Variable Length Messages = CHAOS!

Hi!I have an INS that sends the following frames: Frame 1 of 60 bytes every 40 ms Frame 2 of 70 bytes every 20 ms Frame 3 of 32 bytes every 1s Frame 4 (unwanted, but impossible to deactivate) of almost 500 bytes every 2s. I am implementing receive wi...

Can STM32F105 do 13-bit SPI with 13 clocks?

I need to interface with a Viniculum II from FTDI. It requires 13 bits over exactly 13 clocks, per this app note. We're using the STM32F105 with HAL libraries from STM32CubeMX. I don't see the cube able to configure to 13 clocks. Will the STM32F1...
