Hello,i am working for now on a diy project.In this project i am interfacing LoRa SX1278 (SPI), MPU6050 (I2C) and NEO-6M (UART) with the STM32F103C8 (blue pill).All in all it is working but because all this sensors and modules are served in the loop,...

Hello,for a DIY project including LoRa ra-02, MPU6050 and NEO-6M i have purchased some Blue pills from a vendor but it turned out they are fake blue pills (STM32F103C6).I am trying to make a RC, so i have a Transmitter which needs 2xSPIs (one for LoR...

Hello all,for my DIY Radio Controller (LoRa and STM32F1C8) i am using two joysticks and one poti.I am reading ADC with the DMA but what i noticed is that the ADC values are not so accurate.I know with not (professional, expensive) Potis and joysticks...

Hello,i am trying to interface 1.8 inch SPI TFT Display 128 x 160 to the STM32F103C8 using SPI2.https://www.az-delivery.de/products/1-8-zoll-spi-tft-displaySPI1 is used for LoRa, i thought to connect TFT too to SPI1 using addresses but i am affraid t...

Hello,i have used the library i aploaded to calculate roll, pitch and yaw.I am using MPU6050 with STM32F103C8 and KEIL IDE.For pitch and roll i get good results but i cann't get the result for yaw.I use kalman filter for that.

Thank you all for your suggessions and advices.I will surely work on them and see how can i achieve my goals.

I am running my blue pill at 72 MHz.I haven't descriped the situation correctly.You are right, it has nothing to do with stm32.The issue is with the while loop so many function getting called and therefore transmission must wait till all these functi...

@Andrew Neil You mean this: https://www.u-blox.com/en/product/neo-6-series ?Yes, but i have just noticed that NEO-6M has reached his EOL, lol.

Thank you for the reply.It affects the transmission because it reads the NEO-6M and then decode the result in the same while loop where transmitting the data occurs.Therefore i thought of using free RTOS so it can do this tow tasks parallel? i think....
