Remote LCD Nokia5510/JLX12864 with ESP32

[kagouraki]

I am sorry for the delay. I had a tight schedule.

So in order to compile, this is the steps i followed if someone needs it. 
The Hash lines are comments. You should run the commands one by one in the same terminal session. 

Code:

#organize everything
cd
cd Desktop
mkdir PypilotEsp32
cd PypilotEsp32

#Esp-Idf
git clone https://github.com/espressif/esp-idf.git
cd esp-idf
git fetch
git checkout 4c81978a3e2220674a432a588292a4c860eef27b
git pull
git submodule update --init --recursive
./install.sh
source export.sh
cd ..

#micropython
git clone https://github.com/micropython/micropython.git
cd micropython
git checkout 78b23c3
make -C mpy-cross
cd ports/esp32
make submodules

#now test if everything is compiling
make
#if it finishes without errors continue

cd ../../
mkdir modules
cd modules
git clone https://github.com/pypilot/micropython_ugfx.git
cd ../ports/esp32
nano Makefile

#Now search for DRIVERS_SRC_C = $(addprefix drivers/
and change the following lines from

OBJ_MP =
OBJ_MP += $(PY_O)
OBJ_MP += $(addprefix $(BUILD)/, $(SRC_C:.c=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(SRC_CXX:.cpp=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(EXTMOD_SRC_C:.c=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(LIB_SRC_C:.c=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(DRIVERS_SRC_C:.c=.o))

to

OBJ_MP =
OBJ_MP += $(PY_O)
OBJ_SRC_C = $(SRC_C:.c=.o)
OBJ_MP += $(addprefix $(BUILD)/, $(OBJ_SRC_C:.cpp=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(SRC_CXX:.cpp=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(EXTMOD_SRC_C:.c=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(LIB_SRC_C:.c=.o))
OBJ_MP += $(addprefix $(BUILD)/, $(DRIVERS_SRC_C:.c=.o))

#Save the Makefile and continue with compiling
make BOARD=GENERIC USER_C_MODULES=../../modules CFLAGS_EXTRA="-DMODULE_UGFX_ENABLED=1 -Wno-error=unused-const-variable" all
make erase
make deploy

#now when you connect to your esp32 with picocom -b 115200 /dev/ttyUSB0 you will find out that there is an error

E (767) esp_image: Image length 2008704 doesn't fit in partition length 1572864
E (767) boot: Factory app partition is not bootable
E (769) boot: No bootable app partitions in the partition table

#so we need to change the partition table because there is not enough space

nano partitions.csv

#erase everything and paste this:

# Notes: the offset of the partition table itself is set in
# $IDF_PATH/components/partition_table/Kconfig.projbuild.
# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x6000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000, 0x300000,
vfs,      data, fat,     0x310000, 0xF0000,

#save and continue
make clean
make BOARD=GENERIC USER_C_MODULES=../../modules CFLAGS_EXTRA="-DMODULE_UGFX_ENABLED=1 -Wno-error=unused-const-variable" all
make erase
make deploy

#now if you connect with picocom -b 115200 /dev/ttyUSB0 to your esp32 you should not have any errors
#check with import ugfx if the module is there

I have a esp32 LOLIN32 board. It doesnt have SPIRAM so i needed to change the partition table.
If you have a board with SPIRAM then you can compile with 

make BOARD=GENERIC_SPIRAM USER_C_MODULES=../../modules CFLAGS_EXTRA="-DMODULE_UGFX_ENABLED=1 -Wno-error=unused-const-variable" all


and you probably dont need to change the partition table. I dont know because i dont have such a board handy.

Hope this will help someone. I will now upload the files from pypilot and go Forward. I will write the steps for reference.
