Hi There,
Working on MCF52259 bootloader standard program in C, as per the freescale flowchart, if the program entered into the bootloader function then board have to be reset to exit from bootloader mode. For my application, if there is no mass storage aviable on the bood, I want to exit from...
Dear all,
I would lik to get some advice from you guys that, I need to have about 64 individual time counters to count time for each registor. I have one timer which is going to use this purpose and some other general purpose too. How can I handle effectively instead of doing all counting...
Hi Every body
I am using two msp430f5438 mcu's one set master and other set to slave for data tranfer through spi. When I sen a single char from master micro, the slave micro received correctly. But when I sen a bulk data/structure the slave micro not receive correctly all data. If any one...
Hi Every body,
I am using MSP430F5435A to interface with SAP3305 LCD controller. I could not able to light up the LCD, Coud any one help me to see my code and correct. I am not sure it is because of timing issue. The SAP3305 controller and RA8835 are same.
the code is bellow,
#include...
Hi Friends,
I have developed a communication in between two microcontrollers through UART. Just send a char from Main micro and received the char by Slave micro successfully. Basically the slave micro is there for update 240X240 pixels dot matrix LCD. So what ever the data send from Main micro...
This is water analyses meter. measure pH, conductivity, DO, mV so on. So once the meter ON it start to measure the parameters as above and update on the LCD continuously. I will re check ARM7 as well. Thanks you.
Hi Thank you again,
The device specified to work 1000 hour on normal mode (without backlight) with 4 alkaline battories (6V). LCD is monochrome 320 X 240 pixls QVGA.
according to my knowledge, if I am not wrong current for ARM is around 1.5 mA/MHz. If I operate the arm at 16MHz the CUP current...
Re: Advice me!!
Hi
Thanks your post.
Actually my concern is mainly on CPU power consumption. Becouse the device is going to be hand held so the design should be capable for low power consumption. Thats why I wanted to use MSP430, at the same time, I needed around 25K RAM and 300K flash...

hi all,
if any one done with msp430f5438 and microchip serial eeprom (24lc512) I2C bus communication by using I2C module pls hel me to do. I cant able to communicate properly. these are the main functions,
EEPROM_ByteWrite(0x0000,0x12);
EEPROM_AckPolling(); // Wait for EEPROM write...
msp430f5438
Hi all,
I am using MSP430F5438 for my project. I need to set the basic timer to enable from LPM3 according my time specification. In the MSP430F5438 user manual they mention that the RTC module can be configure general purpose counter / real time clock. I have already configured...
data base build
hi,
if any one help me to build a data base using EEPROM read values. Eg:
My data base,
typedef struct{
int read;
int write;
unsigned long address;
int secon;
int minit;
int hour;
int dd;
int mm;
int yy;
char temp;
}Data;
my eeprom reading values always 1...
pls help me!!
hi
I am using msp430f5438 mcu, and communicate eeprom via i2c. I can not do it successfuly. Pls if any body done for msp430f5xx family share with me.
thanks
I2C
Hi
Pls help me to use MSP430F5438/5xx I2C module for interfacing EEPROM (24FC1025).
like
InitI2C(); // Initialize I2C module
EEPROM_ByteWrite(0x0000,0x12);
Data[0] = EEPROM_RandomRead(0x0000); // Read from address 0x0000
Data[1] = EEPROM_CurrentAddressRead(); //...
