Simple ADC use on the STM32

Here is a bit of a look at how to use the ADC on the STM32 for simple applications. The ADC peripheral on the STM32 processor is a flexible but complex beast. The peripheral driver library should make it relatively easy to use. After all, there is no need to remember the names of all those pesky registers and bitfields. There are anything up to 18 multiplexed channels that can be converted singly, continually, scanned or discontinuously. The results can be transferred to memory through DMA and some devices have two or more ADCs for simultaneous conversions. With all those options, simple reading of an ADC port is a little tricky…

Nokia 3410 LCD on the STM32

et-arm-stm32-nokia-lcd-1.jpgThe Nokia LCD displays are among my favourite toys. Generally, I use a monochrome display intended for the Nokia 3410 ‘phone. This a display size of 96 x 48 pixels and can display bitmaps as well as text in 6 rows of 16 characters. It is smaller than the more common 16×2 text-only displays, easier to drive, cheaper, uses fewer connections, much more flexible and is readily available. And now, I have connected one up to my STM32F103 Cortex-M3 processor. As a first go with the SPI peripheral on these processors, it has been quite instructive…
