A great electronic, Marko, did a nice project to show, how STM32F070 in 20-pin footprint can be used with USB and LCD. For 20-pin this MCU is very powerful with his 48MHz and USB with some other peripherals. For hardware specification, including schematics and PCB top layer for toner transfer, you can check an original link, posted at the end of this post.
After MPU6050 library for STM32F4xx series only based on STM32F4xx Standard peripheral drivers, I’ve redesign this library for HAL support over all STM32 series. It has some more features then my first library. It can now read data from MPU6050 (obvious), set interrupts for data ready and motion detection, read interrupts status, set custom data rate for data ready interrupt and set new gyro and accelerometer sensitivities on the fly. More about lib is describe below and on HAL API site. Library...
Analog to digital converter library is out. It was a lot of time before I thought why I don’t have this basic library where anyone would use it. Now i exists. This library works on STM32F0xx, STM32F4xx and STM32F7xx based devices. Library Read more about new HAL libraries Features It uses basic polling for ADC complete Supports VBAT reading Does not get high sampling rates Meant for basic use
Here it is. After many email about this library, I’ve finally made it. This library works on STM32F0xx, STM32F4xx and STM32F7xx based devices, where DAC is supported. For example, STM32F401 and STM32F411 does not support DAC. Library Read more about new HAL libraries Features It does not use built-in HAL support for generating signals Output is based on user value Independent 2 DAC channel outputs with 12-bit resolution
If you wanna take a control on your software (secure your software by selecting package you want, device you want and others) you can identify STM32Fxxx device. This library allows you to read several things from device, like unique ID, flash size, package type, device type and maybe more. I’ve ported my old library to HAL based drivers, which now supports STM32F0xx, STM32F4xx and STM32F7xx series. Library Read more about new HAL libraries Features Read device type with software, Read...
I spent some time again porting libraries from STD drivers for F4 series to HAL drivers for STM32 series. This library is going to be about NRF24L01+ transceiver module, allowing you to send and receive data between 2 NRF24L01+ modules connected to STM32Fxxx device. Library Read more about new HAL libraries Features Send and receive data using NRF24L01+ Allows to use IRQ pin on NRF24L01+ Functions to read and clear interrupts are in API
