This appendix describes the proper ID and names for the various peripheral ports and buses for the Keil MCBSTM32F200 embedded board, which are accessible using the Device Access APIs. Note that any IMlet that accesses the Device Access APIs must be digitally signed using a trusted certificate authority. An IMlet that is not signed will encounter an authentication error when attempting to access the Device Access APIs.
The Keil Reference Manual for the MCBSRM32F200 board provides additional technical information about the peripherals accessible via the Device Access APIs.
The following ADC channels are pre-configured.
| DAAPI Peripheral ID | DAAPI Peripheral Name | Mapped To | Configuration |

Additional notes:
There are 48 total channels. For more information on assigned external pins, see the manufacturer board schematics.
For the converter number, acceptable values range from 0 to 2, which map to ADC1 to ADC3 on the device. For the channel number, acceptable values range from 0 to 15. Note that only one channel may be opened on each converter at a time. Consequently, only three channels may be in operation at any one time.
The internal sampling values range from [14857, 46857]. However, the sampling time is ignored.
There are four pulse counters on the board. Each has a GPIO pin source: PA0, PB3, PB10, and PA3. Note that each source has only one counter, so the "number" property is not used for the Keil board.
The following pulse counters are pre-configured:
| DAAPI Peripheral ID | DAAPI Peripheral Name | Mapped To | Configuration |
|---|---|---|---|
|
201 |
COUNTER_PA0 |
“WAKEUP” button connected to PA0 |
counterNumber - not supported / ignored type = PulseCounterConfig.TYPE_FALLING_EDGE_ONLY portNumber = 0 pinNumber = 0 |
|
202 |
COUNTER_PB3 |
PB3 |
counterNumber - not supported / ignored type = PulseCounterConfig.TYPE_FALLING_EDGE_ONLY portNumber = 1 pinNumber = 3 |
|
203 |
COUNTER_PB10 |
PB10 |
counterNumber - not supported / ignored type = PulseCounterConfig.TYPE_FALLING_EDGE_ONLY portNumber = 1 pinNumber = 10 |
|
204 |
COUNTER_PA3 |
PA3 |
counterNumber - not supported / ignored type = PulseCounterConfig.TYPE_FALLING_EDGE_ONLY portNumber = 0 pinNumber = 3 |
There are no pulse counters available ad-hoc.

WARNING: The information in this appendix is presented in addition to the board schematics provided by the manufacturer. Be sure to familiarize yourself with the manufacturer's documentation for all of the GPIO pins. Failure to do so can result in damaged peripherals or even a damaged embedded board. |
The following GPIO pins are available ad-hoc. Note that some GPIO pins are used at the system level, so opening those pins may affect board behavior.
Accepted port numbers are PA=0, PB=1, PC=2, PD=3, PE=4, PF=5, PG=6, PH=7, PI=8.
Accepted pins number are from 0 to 15.
Depending on the board, PB0 and PB1 may be unused.

Note that the addresses [0x2001FE00 - 20020000) are part of the external RAM reserved for MMIO, and any type will be allowed. In addition, the addresses [0x40000000 - 0x50060C00) and [0xA0000000 - 0xA0001000) are peripheral IO registers. Be sure to check the manufacturer's documentation for actual sizes, type and valid values. With each of the addresses above, the final address is non-inclusive.

The are no UART devices available ad-hoc.
The deviceaccess.uart.prefix property in the jwc_prop.ini file may contain a prefix for easy conversion of the UARTConfig.portNumber value to a platform-specific port name. For example, the property may be set to "COM" in a Windows environement, or "UART" in a Keil environment such that appending on a port number will correctly map to the port name.
