How to enable the FPU in Atollic for the STM32F4-Discovery
Posted on March 14, 2014 at 16:03If someone could give me an idea, that'd be great. I need it to speed up math operations.

Resolved! STM32F030RC: a 'software reset' and 'outside the program code' after pressing debugger 'resume' button
Hi everyone,we have prototype with three STM32F030RC and with very strange behavior. All mcu has shared NRST (pulled up, for testing not externally driven) and BOOT0 (for testing pulled low permanently) pins. For a testing purpose I created clean pro...
Resolved! Unable to transmit CAN signal on Bluepill.
I am transmitting a CAN signal using bluepill but there is no signal on the CAN Bus. I added two counters which will check whether transmission was successful with the following code.if(HAL_CAN_AddTxMessage(&hcan, &TxHeader, TxData, &TxMailbox) == HA...
HRTIMER Windowing
I'm using the HRTIMER_F on an STM32G474 running both TF1 and TF2 (half mode with deadtime insertion)I'm trying to setup a window where a capture from an external event can occur (COMP3_OUT). The interrupt from the capture is triggered regardless of t...
LPUART1 with DMA - STM32U575RG / NEO-M8N
Hello, I am using the STM32U575RG microcontroller, and I am developing a board with a NEO-M8N model GPS, and I am using LPUART1. However, I am wanting to implement it with DMA. Could someone help me explain how to configure the microcontroller with D...
STM32F745ZG ethernet high payload transmission problem
Hi,I have been trying to implement a TCP server on a STM32F745ZG MCU using lwip library and ST example codes, however while I am trying to send data packets with payload bigger than 1460 bytes, my server wont be able to replay the client packet and t...
Resolved! Two different STM32U031K8U6 MCU have randomly entered RDP 1 mode without instructions to do so.
I have been looking at the power consumption on an STM32U031K8U6 when it is put into standby mode with the RTC setup to regularly wake up the processor. Most recently I had the wake-up time set to 250ms. The processor wakes up and does the following-...
STM32H573I-DK_aws_ri_tz certificate
I'm working with the stm32h573i-dk kit and I need a connection to AWS. I performed the step-by-step procedure as described in the webinar https://content.st.com/stm32h5-connects-smart-things-in-a-secure-way.html, however, I got stuck at the end, wher...
Resolved! STM32F303VC clock setup with crystal on OSC_IN
We have custom HW with an STM32F303VC processor.There is a 12 MHz crystal with an 18pF in parallel wired to OSC_IN and OSC_OUT.The power budget is basically unlimited so we would like to run the device as fast as possible with this configuration.Peri...
STM32F4 Timer Counter Never Starts Counting
Hi, I am attempting to enable TIM1 to act as my program's tick timebase as SysTick is being utilized by the FreeRTOS kernel to generate PendSV interrupts. I configured this in CubeMX (Timebase set to TIM1) but I cannot get TIM1 to start ticking. Atta...
