Hello All, I am trying to get my LCD to work but my data is sent via GPIOC 0...7 and GPIOB 8...15 and for the life of me I cannot get it to work. All I am trying to do is get the gdisp circle demo going.. Below are my board file and driver file.. Please just a kick in the right direction would be appreciated. board.h #ifndef _BOARD_H_ #define _BOARD_H_ /* * Setup for the ST INEMO-M1 Discovery board. */ /* * Board identifier. */ #define BOARD_OLIMEX_STM32_LCD #define BOARD_NAME "Olimex STM32-LCD" /* * Board frequencies. */ #define STM32_LSECLK 32768 #define STM32_HSECLK 8000000 /* * MCU type, supported types are defined in ./os/hal/platforms/hal_lld.h. */ #define STM32F10X_MD /* * IO pins assignments. */ #define GPIOA_KEY1 0 #define GPIOA_KEY2 1 #define GPIOA_LED1 2 #define GPIOA_LED2 3 #define GPIOA_SPI1_NSS 4 #define GPIOA_SPI1_SCK 5 #define GPIOA_SPI1_MISO 6 #define GPIOA_SPI1_MOSI 7 #define GPIOA_PA8 8 /* FREE PA8/USART1_CK/TIM1_CH1/MCO */ #define GPIOA_USART1_TX 9 #define GPIOA_USART1_RX 10 #define GPIOA_PA11 11 #define GPIOA_PA12 12 #define GPIOA_SWDIO 13 #define GPIOA_SWCLK 14 #define GPIOA_PA15 15 #define GPIOB_PB0 0 /* VR */ #define GPIOB_PB1 1 /* FREE PB1/ADC12_IN9/TIM2_CH4/TIM1_CH3N */ #define GPIOB_PB2 2 /* BOOT */ #define GPIOB_PB3 3 /* JTAG JTDO */ #define GPIOB_PB4 4 /* JTAG JNTRST */ #define GPIOB_LE 5 #define GPIOB_F_CS 6 #define GPIOB_SD_CS 7 #define GPIOB_DB08 8 #define GPIOB_DB09 9 #define GPIOB_DB10 10 #define GPIOB_DB11 11 #define GPIOB_DB12 12 #define GPIOB_DB13 13 #define GPIOB_DB14 14 #define GPIOB_DB15 15 #define GPIOC_DB00 0 #define GPIOC_DB01 1 #define GPIOC_DB02 2 #define GPIOC_DB03 3 #define GPIOC_DB04 4 #define GPIOC_DB05 5 #define GPIOC_DB06 6 #define GPIOC_DB07 7 #define GPIOC_CS 8 #define GPIOC_RS 9 #define GPIOC_WR 10 #define GPIOC_RD 11 #define GPIOC_BL_EN 12 #define GPIOC_TP_INT 13 #define GPIOC_PC14 14 #define GPIOC_PC15 15 #define GPIOD_OSC_IN 0 #define GPIOD_OSC_OUT 1 #define GPIOD_PD2 2 /* * I/O ports initial setup, this configuration is established soon after reset * in the initialization code. * * The digits have the following meaning: * 0 - Analog input. * 1 - Push Pull output 10MHz. * 2 - Push Pull output 2MHz. * 3 - Push Pull output 50MHz. * 4 - Digital input. * 5 - Open Drain output 10MHz. * 6 - Open Drain output 2MHz. * 7 - Open Drain output 50MHz. * 8 - Digital input with PullUp or PullDown resistor depending on ODR. * 9 - Alternate Push Pull output 10MHz. * A - Alternate Push Pull output 2MHz. * B - Alternate Push Pull output 50MHz. * C - Reserved. * D - Alternate Open Drain output 10MHz. * E - Alternate Open Drain output 2MHz. * F - Alternate Open Drain output 50MHz. * Please refer to the STM32 Reference Manual for details. */ #define VAL_GPIOACRL 0x88384B88 /* PA7...PA0 */ #define VAL_GPIOACRH 0x88888883 /* PA15...PA8 */ #define VAL_GPIOAODR 0xFFFFBFDF /* * Port B setup. * Everything input with pull-up except: * PB3 - Pull-up input (GPIOA_SWO). */ #define VAL_GPIOBCRL 0x88388888 /* PB7...PB0 */ #define VAL_GPIOBCRH 0xBBBBBBBB /* PB15...PB8 */ #define VAL_GPIOBODR 0xFFFFFFFF /* * Port C setup. * Everything input with pull-up except: * PC13 - Normal input (GPIOC_BUTTON). */ #define VAL_GPIOCCRL 0xBBBBBBBB /* PC7...PC0 */ #define VAL_GPIOCCRH 0x8847BBBB /* PC15...PC8 */ #define VAL_GPIOCODR 0xFFFFFFFF /* * Port D setup. * Everything input with pull-up except: * PD0 - Normal input (GPIOD_OSC_IN). * PD1 - Normal input (GPIOD_OSC_OUT). */ #define VAL_GPIODCRL 0x88888844 /* PD7...PD0 */ #define VAL_GPIODCRH 0x88888888 /* PD15...PD8 */ #define VAL_GPIODODR 0xFFFFFFFF /* * Port E setup. * Everything input with pull-up except: */ #define VAL_GPIOECRL 0x88888888 /* PE7...PE0 */ #define VAL_GPIOECRH 0x88888888 /* PE15...PE8 */ #define VAL_GPIOEODR 0xFFFFFFFF /* * USB bus activation macro, required by the USB driver. */ #define usb_lld_connect_bus(usbp) /* * USB bus de-activation macro, required by the USB driver. */ #define usb_lld_disconnect_bus(usbp) #if !defined(_FROM_ASM_) #ifdef __cplusplus extern "C" { #endif void boardInit(void);
