Using the inline compiling macro ?

I have an LCD is on an 8080 16bit FMC interface with A0 register select.

I can read the status correctly here:

#define LCD1_DEVICE_ADDR (uint32_t)0x60000000
#define LCD1_DEVICE_DATA (uint32_t)0x60000001
 
 uint16_t *pLcdRStatusWAddress = LCD1_DEVICE_ADDR;
 readLcdStatus = *pLcdRStatusWAddress;

All of these snippets are within one file,

//this compiles:
 
inline lcdRegDataWrite(uint8_t reg, uint8_t data) {
 *(__IO uint16_t*)LCD1_DEVICE_ADDR = reg; 
 *(__IO uint16_t*)LCD1_DEVICE_DATA = data; 
} 
 
//but this doesn't find it
 
 lcdRegDataWrite( 1 , 8);
 
>>> undefined reference to `lcdRegDataWrite'

Hi @Community member ,

Could you please provide more details on your case: which compiler? which device? is this your own code or found in an example provided by ST?...

Check with your compiler vendor, review example others are using and that work

Yes, I renamed it for the forum, .. well spotted..

I added the Void but that didn't help.

inline void lcdRegDataWriten(char reg, char data) {
// *(__IO uint16_t*)LCD1_DEVICE_ADDR = reg; 
// *(__IO uint16_t*)LCD1_DEVICE_DATA = data; 
 *(__IO uint16_t*)0x60000000 = reg; 
 *(__IO uint16_t*)0x60000001 = data; 
}

Okay so post the whole offending file which caused the output above, or post the file together with the output, so we have a complete view.

Also, try to add a line

#error "no compile"

just below the line

inline void lcdRegDataWriten(char reg, char data) {

thanks for the pointers @Community member, @Community member

was this the output you expected ?

1> #error "no compile"

and this is the current code:

inline void lcdRegDataWriten(char reg, char data) {
#error "no compile"
// *(__IO uint16_t*)LCD1_DEVICE_ADDR = reg; 
// *(__IO uint16_t*)LCD1_DEVICE_DATA = data; 
 *(__IO uint16_t*)0x60000000 = reg; 
 *(__IO uint16_t*)0x60000001 = data; 
}

this is the usage:

 lcdRegDataWriten(1, 8);
 
 
with #error compile removed:

sorry for the delayed response

Post the sources, possibly reduced to a bare minimum which still compiles and produces the problem.

is this what you are after ?

Yes.

And you have compiled and linked this and it still threw the above error?
