Posted on April 18, 2016 at 13:55Folks, I have a complicated set-up where I am receiving serial data via an RS485 transceiver. The USART Rx reads three bytes, looks at those three bytes and works out how many more bytes will be in the remainder of ...
Posted on April 13, 2016 at 12:51Hi everyone,I�ve implemented a websocket client that runs on a STM32F4 with FreeRTOS and lwIP 1.4.1.The client is supposed to send the machine status to the server each 5 seconds (plain text message).I let the client...
Posted on April 13, 2016 at 01:28Hi, I'm currently thinking about anti-bounce for button inputs on my design and this brought me to the above question. As I'd like to avoid adding an extra schmitt-trigger for cost reasons, I'm doing the anti-bounce ...
Posted on April 16, 2016 at 23:47Hello,I'm working on a cpu intensive project involving CAN bus.My idea is to use all the 3 available TX mailboxes.I do my processing, fill up the mailboxes and trigger the transmission. Transmission is started just a...
Posted on April 16, 2016 at 07:17Hi,I am using STM32F103 and keil compiler.I am configuring CAN, but while configuring I got small doubts.As we know CAN is multi-Master protocol. But in data sheet i can see (CAN1 Master) an CAN2 as Slave.Can anybody...
Posted on April 09, 2016 at 16:45Hello,I wanna calculate the motor speed using timer of STM32F4. I wanna know the time spended in one revolution. So , who would explain for me how can I do that . thanks a lot.
Posted on December 30, 2015 at 23:27 Hello everyone! I'm having troubles using timer interrupts in with Mbed and aSTM32F7 discovery kit. I thought about using Mbed's ''ticker'', but I need an interrupt every 0.125us (8MHz). ...
Posted on May 23, 2013 at 17:11Hello,I want to do something ''simple'': measuring the time duration between two button presses. In my application, the user can press a button repetitively and the STM32F4 will calculate the time between two pulses to...
Posted on May 08, 2014 at 23:04Hello everybody. I have a working code with stm32f407 and freertos. I want to use stop mode at the microcontroller. I read the tickless mode at freertos, this is for use the sleep mode. If I define this mode, my code g...
Posted on April 15, 2016 at 09:43Hi I am having trouble in accessing the external NOR flash on STM32F407 device. As per the user's manual, the FSMCs have been set up but the I doubt whether it's correct or not. Has anyone tried it before or do ST ha...
