const unsigned char  FONT8x8ASCII[][8] = {
/* 空格 */
  {
________,
________,
________,
________,
________,
________,
________,
________}

/*  !  */
,{
___XX___,
__XXXX__,
__XXXX__,
___XX___,
___XX___,
________,
___XX___,
________} };
为什么我在Keil定义上面FONT8x8ASCII就提示出错

ASCII字符要用'',比如'A'
字符串用"".....

1.以上在ADS上定义是没有问题的.
2.在Keil中定义
const unsigned char  FONT8x8ASCII[][8] = {
/* 空格 */
  {
"________",
"________",
"________",
"________",
"________",
"________",
"________",
"________"}

/*  !  */
,{
"___XX___",
"__XXXX__",
"__XXXX__",
"___XX___",
"___XX___",
"________",
"___XX___",
"________"} };
出错:T.C(13): error C243: 'array[]': string out of bounds

FONT8x8ASCII[][8]改成FONT8x8ASCII[][9]

''只能用于单个字符
""这个用于字符串
真怀疑你是不是写程序的

应该是有头文件没包含进来
________这个都没有定义
#define ________ 0x00
#define _______X 0x01
#define ______X_ 0x02
#define ______XX 0x03
#define _____X__ 0x04
#define _____X_X 0x05
