This is a "get in touch with" project for the stm32f100 MCU nested in the discovery board. For further information on the board go to:
http://www.st.com/internet/evalboard/product/250863.jsp
Goals
The primary goal is to get in touch with the stm32f100 and CooCox CoIDE.
There are also specific software interest like
- General Purpose of the uController (Timers, Interrupts... )
- UART (or USART) communications
- In-Application-Programming (IAP) with I/O Peripherals like USART...
After evaluation of the internals, there will be also an evaluation on the
hardware. If everythings going on well, there will be an selfmadeboard
based on the stm23f1xx. There is also an interest to run a selfmade basic
vm on the MCU.
Current stats on SW Development
OK Initializing the general functions of the MCU (clock settings)
OK Sending data from the MCU to USART
OK Receiving data from USART to MCU per Interrupt
CD Initialise and run ISR (Interrupt Sevice Routines) [30% developed yet]
ND Timers (Init, Interrupt etc.)
Indexes
OK = get it work
CD = currently on development
ND = not developed yet but in agenda
Configuration for current development/debugging/testing
OS: Windows, XP, SP3
IDE: CooCox CoIDE (Version: 1.4.1, Build id: 20120401-1336)
Terminal: Tera Term
Toolchain: arm-none-eabi-gcc
USB/Serial: CP2102
Board-External I/O: 4D Systems 3.2" uLCD SGC
Digital-Analyzer: DigiView TechTools Logic Analyzer DV1-100 (18 Channel)
Coming soon: RIGOL DS1052E Digital Storage Oscilloscope
The main setting to develop and test the source is like this:
_______ _____________________ _________
/ \ / | \ / \
| PC | USB | |STM32 | PWR | 4D |
| |--->---| ST-Link |Discovery |--->---| Systems |
| | CP | | | Rx/Tx | 3.2" |
| |-<-x | | |-->x<--| uLCD |
\_______/ | \_________|___________/ | \_________/
| |
|__________(optional!)________|
The connection from the Rx/Tx lines between 4D Sytems uLCD and the STM32
board is not "that" good for debugging the Rx/Tx signals with the CP2102
because of the signal voltage level differences between them. If the
CP2102 is connected to these lines it will disable the Tx of the 4D Systems
Display. So in short:
IF THE CP2102 IS CONNECTED TO THE RX/TX BETWEEN 4D AND STM32,
THEN THE TX OF 4D IS DISABLED (neither able to enable nor detect)
