Dear All,
I have been working on project to develop an HMI for vehicle for prototype purpose I am using MI0283QT-9A TFT display in SPI mode want it to work with my customized board using STM32F103CBT6. Currently I my using ILI9341 drivers available online and for their project it works where they used STMBlue pill.
Mentioning detail of SPI and GPIO selection I made:
1)SPI: pre scale: 64, Mode: transmit only master, Frame format: Motorola, 8bits ,First bit MSB,Baud rate:1.12MBits/sec
2)GPIO: CS(GPIO_out=Low),D/C(GPIO_out=High),RST(GPIO_out=High)
Connection:
IM0=L, IM1=H,IM2=H,IM3=0.
RS---> SCK
WR---> D/C
CS ----> CS
RD---> VCC
D0-D17--->GND
SDI ----> MOSI
SDO ----> MISO
Issues and observations:
1) The SPI communications starts MOSI send some packets SCK is have 1.1MHz stay active for 10 sec and stops, this activity is done after every resent or turn ON. Verified on CRO.
2) The LCD backlight turns ON and doesn't display anything
For reference I have provide links of library and ILI9341 datasheet and attached my current code and data sheet from LCD manufacturer.
Kindly help me to activate my display
Hope this is enough data to guide me.
Regards.
