PA5, MOSI to PA7 and MISO to PA6. Note: some chinese boards use MOSO instead
of MISO.
Nokia 5110 LCD Display support:
===============================
You can connect a low cost Nokia 5110 LCD display in the STM32F103 Minimum
board this way: connect PA5 (SPI1 CLK) to CLK; PA7 (SPI1 MOSI) to DIN; PA4
to CE; PA3 to RST; PA2 to DC. Also connect 3.3V to VCC and GND to GND.
You can start with default "stm32f103-minimum/nsh" configuration option and
enable these options using "make menuconfig" :
System Type --->
STM32 Peripheral Support --->
[*] SPI1
Device Drivers --->
-*- SPI Driver Support --->
[*] SPI exchange
[*] SPI CMD/DATA
Device Drivers --->
LCD Driver Support --->
[*] Graphic LCD Driver Support --->
[*] Nokia 5110 LCD Display (Philips PCD8544)
(1) Number of PCD8544 Devices
(84) PCD8544 X Resolution
(48) PCD8544 Y Resolution
Graphics Support --->
[*] NX Graphics
(1) Number of Color Planes
(0x0) Initial background color
Supported Pixel Depths --->
[ ] Disable 1 BPP
[*] Packed MS First
Font Selections --->
(7) Bits in Character Set
[*] Mono 5x8
Application Configuration --->
Examples --->
[*] NX graphics "Hello, World!" example
(1) Bits-Per-Pixel
After compiling and flashing the nuttx.bin inside the board, reset it.
You should see it:
NuttShell (NSH)
nsh> ?
help usage: help [-v] [<cmd>]
[ dd free mb sh usleep
? echo help mh sleep xd
cat exec hexdump mw test
cd exit kill pwd true
cp false ls set unset
Builtin Apps:
nxhello
Now just run nxhello and you should see "Hello World" in the display:
nsh> nxhello
USB Console support:
