This is so weird.
I build this simple bpfilter.
I used t50-6 amidon.
I want it for 18.1 Mhz.
So, in spice its perfect with either 3300pf and 24nH... Or 2200pf and 35nH.
(2 or 3 turns, inductor).
I tried both.
As you se it works over 18 Mhz in spice but then i build it for real the bandpass...
I need to send a series of bits, one at at time throu GPIOc port c6-c9.
I will show you the part of code that is intresting here.
I will use this ports:
PC9 - W_CLK
PC8 - FQ_UD
PC7 - DATA
PC6 - RESET
I use push pull and speed 2 MHz.
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP...
"Makefile", "ST7735.c", "ST7735.h", "glcdfont.c", "main.c", "spi.c" and "spi.h" is files i want to put in my project-window in coocox...
Files i found on github that are only to download and get my lcd runing.
But were to put them?
There is "cmsis" and "startup"-folders and also "include" and...
that dds just doesent work.
Have i done something wrong with my code?
Anyone?
Any ideas?
#include <stm32f10x.h>
#include <stm32f10x_rcc.h>
#include <stm32f10x_gpio.h>
int main(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC , ENABLE); //...
